As a radioactive sample decays in a glass vacuum container, and the released alpha particles collide with the glass, would it be correct to assume that the particles "bounce around?"
Thanks, just what I was looking for.Pretty much what he said. For more detail see:
If by "bounce around" you mean, off the walls of the container - no.
Energetic alphas may scatter off the nuclei, some may back-scatter... but really you expect absorption.
On the scale of the individual alpha, the glass is a kind of fog with hard points in it.
Alpha particle tracks in a cloud chamber:
... illustrates the short range, with deflection/absorbtion by denser matter.
Alphas are the same as doubly-ionized helium atoms - different origin though.Thanks, just what I was looking for.
So in a man made vacuum, it would be expected for some α-particles to be absorbed by the glass, while others would ionize into helium gas inside the chamber, correct?
Immediate origins. Perhaps you prefer "processes"?What do you mean by different origins?
Assuming Earthly sources, bearing in mind the above: It mainly comes out of holes in the ground, but I mostly get it from the gasses cupboard at the back of the lab.Where do you think helium comes from? (Assuming Earthly sources)
